I really did only break the three eggs in total - the secret as they say is all in the preparation. I really didn't want to use up loads of eggs for this shot - I was born in 1954 so I had a ration card and I still feel a bit bad about playing around with food

So - I triple checked the focus of the camera, clapped my hands to set off the flashes a few times, triple checked the alignment of the rifle, and tested the bulb setting on the electronic shutter switch a couple of times all before taking the shot. All the preparation seems to have paid off in no wasted eggs
